Review of ODOT’s Overlay Design Procedure, Volume 2: PCC Overlays of Existing Composite Pavements

ODOT initiated this research study to determine (1) the impact of milling off portions of the existing pavement on the structural capacity of the remaining pavement and (2) whether currently recommended HMA structural coefficients adequately reflect the structural properties of new HMA overlay materials. The study mainly focused on the impact of milling on the design of HMA overlays over existing flexible pavements and composite pavements. However, the impact of milling of composite pavements on unbonded overlay design was also another objective of this study. This volume deals with the latter objective and presents findings of a detailed evaluation of four composite pavement projects (eight pavement test sections) located in Southeast Ohio. The report presents descriptions of the data collected, data analysis, observations, and recommendations for improvements of the current ODOT overlay design procedure.
